Excel shall order Two-Way Interconnection Trunks by submitting ASRs to Verizon setting forth the number of Two-Way Interconnection Trunks to be installed and the requested installation dates within Verizon’s effective standard intervals or negotiated intervals, as appropriate. Excel shall complete ASRs in accordance with OBF Guidelines as in effect from time to time. 2.4.11 Verizon may (but shall not be obligated to) monitor Two-Way Interconnection Groups using service results for the applicable design blocking objective. If Verizon observes blocking in excess of the applicable design objective on any Tandem Two-Way Interconnection Trunk group and Excel has not notified Verizon that it has corrected such blocking, Verizon may submit to Excel a Trunk Group Service Request directing Excel to remedy the blocking. Upon receipt of a Trunk Group Service Request, Excel will complete an ASR to augment the Two-Way Interconnection Trunk Group with excessive blocking and submit the ASR to Verizon within five (5) Business Days. 2.4.12 The Parties will review all Tandem Two-Way Interconnection Trunk groups that reach a utilization level of seventy percent (70%), or greater, to determine whether those groups should be augmented. Excel will promptly augment all Tandem Two-Way Interconnection Trunk groups that reach a utilization level of eighty percent (80%) by submitting ASRs for additional trunks sufficient to attain a utilization level of approximately seventy percent (70%), unless the Parties agree that additional trunking is not required. For each Tandem Two-Way Interconnection Trunk group with a utilization level of less than sixty percent (60%), unless the Parties agree otherwise, Excel will promptly submit ASRs to disconnect a sufficient number of Interconnection Trunks to attain a utilization level of approximately sixty percent (60%) for each respective group, unless the Parties agree that the Two-Way Interconnection Trunks should not be disconnected. In the event Excel fails to submit an ASR for Two-Way Interconnection Trunks in conformance with this section, Verizon may xxxx Excel for the excess Interconnection Trunks at the applicable Verizon rates. 2.4.13 Because Verizon will not be in control of when and how many Two-Way Interconnection Trunks are established between its network and Excel’s network, Verizon’s performance in connection with these Two-Way Interconnection Trunk groups shall not be subject to any performance measurements and remedies under this Agreement, and, except as otherwise required by Applicable Law, under any FCC or Commission approved carrier-to-carrier performance assurance guidelines or plan. 2.4.14 Upon three (3) months prior written notice and with the mutual agreement of the Parties, either Party may withdraw its traffic from a Two-Way Interconnection Trunk group and install One-Way Interconnection Trunks to the other Party’s relevant POI, provided that, if a Party has failed to comply with this Agreement with regard to Two-Way Interconnection Trunks, the other Party may upon three (3) months prior written notice and without mutual agreement of the non-complying Party, withdraw its traffic from a Two-Way Interconnection Trunk group and install One-Way Interconnection Trunks to the non-complying Party’s relevant POI. 2.4.15 Excel will route its traffic to Verizon over the End Office and Tandem Two-Way Interconnection Trunks in accordance with SR-TAP-000191, including but not limited to those standards requiring that a call from Excel to a Verizon End Office will first be routed to the End Office Interconnection Trunk group between Excel and the Verizon End Office. 2.4.16 When the Parties implement Two-Way Interconnection Trunks, the Parties will work cooperatively to calculate a Proportionate Percentage of Use (“PPU”) factor for each facility on which the Two-Way Interconnection Trunks ride, based on the total number of minutes of traffic that each Party sends over the Two-Way Interconnection Trunks riding on that facility. Excel will pay a percentage of Verizon’s monthly recurring charges for each facility on which the Two-Way Interconnection Trunks ride equal to Excel’s percentage of use of that facility as shown by the PPU. The PPU shall not be applied to calculate the charges for any portion of a facility that is on Excel’s side of Excel’s-IP, which charges shall be solely the financial responsibility of Excel. During the first full calendar quarter (and any partial calendar quarter preceding such first full calendar quarter) after the first Two-Way Interconnection Trunk is established on a facility, the PPU for that facility will be fifty percent (50%) for each Party. For each calendar quarter thereafter, the Parties shall recalculate the PPU using actual traffic usage data for the preceding calendar quarter. Non-recurring charges for the facility on which the Two-Way Interconnection Trunks ride shall be apportioned as follows: (a) for the portion of the facility on Verizon’s side of the Excel-IP, Excel shall pay fifty percent (50%) of the Verizon non-recurring charges; and, (b) for the portion of the facility on Excel’s side of the Excel-IP, Excel shall be solely responsible for the non-recurring charges.

Upon receipt of a Trunk Group Service Request, Excel Reconex will complete an ASR to augment the Two-Way Local Interconnection Trunk Group with excessive blocking and submit the ASR to Verizon within five (5) Business Days. 2.4.10 Any Tandem Two-Way Local Interconnection Trunk group between the Reconex’s POI and a Verizon Tandem will be limited to a maximum of 240 trunks unless otherwise agreed to by the Parties. In the event that any] Two-Way Local Interconnection Trunk group exceeds the 240 trunk level at any time, Reconex shall promptly submit an ASR to Verizon to establish new or additional End Office Trunk groups to insure that such Tandem Two-Way Local Interconnection Trunk group does not exceed the 240 trunk level. 2.4.11 Upon request, Reconex will submit a written report to Verizon each month setting forth trunk utilization information and percentages. Reconex will calculate utilization percentages by using a traffic data analyzation system specified by Verizon, industry standard study periods and a time consistent busy hour. 2.4.12 The Parties will review all Tandem Two-Way Local Interconnection Trunk groups that reach a utilization level of seventy percent (70%), or greater, to determine whether those groups should be augmented. Excel Reconex will promptly augment all Tandem Two-Way Local Interconnection Trunk groups that reach a utilization level of eighty percent (80%) by submitting ASRs for additional trunks sufficient to attain a utilization level of approximately seventy percent (70%), unless the Parties agree that additional trunking is not required. For each Tandem Two-Way Local Interconnection Trunk group with a utilization level of less than sixty percent (60%), unless the Parties agree otherwise, Excel Reconex will promptly submit ASRs to disconnect a sufficient number of Local Interconnection Trunks to attain a utilization level of approximately sixty percent (60%) for each respective group, unless the Parties agree that the Two-Way Interconnection Trunks should not be disconnected. In the event Excel Reconex fails to submit an ASR for Two-Way Local Interconnection Trunks in conformance with this section, Verizon may xxxx Excel Reconex for the excess Local Interconnection Trunks at the applicable Verizon ratesrates provided for in the Pricing Attachment. 2.4.13 The performance standard on final Two-Way Local Interconnection Trunks shall be that no such Local Interconnection Trunk group will exceed its design blocking objective (B.005 or B.01, as applicable) for three (3) consecutive calendar traffic study months. 2.4.14 Because Verizon will not be in control of when the timing and how many sizing of the Two-Way Local Interconnection Trunks are established between its network and ExcelReconex’s network, Verizon’s performance in connection with on these Two-Way Local Interconnection Trunk groups shall not be subject to any performance measurements and remedies under this Agreement, and, except as otherwise required by Applicable Law, under any FCC or Commission approved carrier-to-carrier performance assurance guidelines or plan. 2.4.14 2.4.15 Upon three (3) months prior written notice and with the mutual agreement of the Parties, either Party may withdraw its traffic from a Two-Way Local Interconnection Trunk group and install One-Way Local Interconnection Trunks to the applicable POI. 2.4.16 Notwithstanding any other Party’s relevant POIprovision of this Agreement, provided that, if a Party has failed to comply with this Agreement with regard to Two-Way Interconnection Trunks, the other Party may upon three (3) months prior written notice and without mutual agreement of the non-complying Party, withdraw its traffic from a Two-Way Interconnection Trunk group and install One-Way Local Interconnection Trunks to the non-complying Party’s relevant POIshall only carry Local Traffic, IntraLATA Toll Traffic and Internet Traffic. 2.4.15 Excel 2.4.17 Reconex will route its traffic to Verizon over the End Office and Tandem Two-Way Local Interconnection Trunks in accordance with SR-TAP-000191TAP192, including but not limited to those standards requiring that a call from Excel Reconex to a Verizon End Office will first be routed to the End Office Local Interconnection Trunk group between Excel Reconex and the Verizon End Office. 2.4.16 2.4.18 When the Parties implement Two-Way Local Interconnection Trunks, the Parties will work cooperatively to calculate a Proportionate Percentage of Use (or “PPU”) factor for each facility on which the Two-Way Interconnection Trunks ride” factor, based on the total number of minutes of traffic Traffic that each Party sends originates over the Two-Way Local Interconnection Trunks riding on that facilityTrunks. Excel Reconex will pay a percentage of Verizon’s monthly recurring charges for each the facility on which the Two-Way Local Interconnection Trunks ride equal to ExcelReconex’s percentage of use of that the facility as shown by the PPU. The PPU shall not be applied to calculate the charges for any portion of a facility that is on ExcelReconex’s side of Excel’sReconex’s-IP, which charges shall be solely the financial responsibility of Excel. During the first full calendar quarter (and any partial calendar quarter preceding such first full calendar quarter) after the first Two-Way Interconnection Trunk is established on a facility, the PPU for that facility will be fifty percent (50%) for each Party. For each calendar quarter thereafter, the Parties shall recalculate the PPU using actual traffic usage data for the preceding calendar quarterReconex. Non-recurring charges for the facility on which the Two-Way Interconnection Trunks ride shall be apportioned as follows: (a) for the portion of the facility Trunks on Verizon’s side of the ExcelReconex-IP, Excel shall pay fifty percent (50%) of the Verizon non-recurring chargescharges shall be divided equally between the Parties; and, (b) for the portion of the facility Trunks on ExcelReconex’s side of the ExcelReconex-IP, Excel Reconex shall be solely responsible for the non-recurring charges. Notwithstanding the foregoing provisions of this Section 2.4.162.4.18, if Excel Reconex fails to provide Excel-IPs at Verizon’s Tandem or End Office(s) in accordance with this Agreement, Excel Reconex will be responsible for one hundred percent (100%) of all recurring and non-recurring charges associated with Two-Way Local Interconnection Trunk groups until Excel Reconex establishes such Excel-IPs.
